I was guest at L3D in October/November 2001 as part of my PhD project.

My own research is on the use and the benefits of graspable resp. tangible
user interfaces for cooperative design situations. Thus I was interested in
assessing the EDC in cooperative settings and learning more about the design
of graspable interfaces.

Working with Hal and Eric on the EDC and the PitA-Board

What have we been doing?:

We designed a scenario for a role play with external subjects in
order to assess two different versions of the EDC. We taped the sessions
on video for analysis. The role play experiment together with participants
feedback allowed us to compare some strength and weaknesses of the different
technologies, gave us ideas for design improvements, and suggested avenues
for further research.
